My family of 4 (two kids 12 and 10) really enjoyed our Western Caribbean cruise on the Dawn. It was our first cruise.
Pros:
1. The ship is in excellent condition, and service was excellent. Our mini-suite with balcony was perfect for us. I particularly appreciated the design of the bathroom. Even though it's just one room, the toilet and shower can both be closed off from the sink area.
Very comfortable. Everything worked. Loved the bathroom layout. Steward was great.
Harvest Caye is what happens when a cruise line develops an Island. The pool and beach were fantastic and immaculate. The island is stunning. But don't kid yourself. This is not Belize. It's an extension of whatever cruise ship you are on.
